they have GOT to stop talking about Game of Thrones in this show
For those hating Daemon's arc right now...
He's being humbled and having demons exorcised. He went there to raise an army for himself and he's finding out he can't issue policy as a king and the castle/witch is putting his personal flaws in front of him (ordering hits on children, being lustful enough to not sense his own mother (she died in his infancy but still), seducing his niece for power).
If he survives the season then this exorcism gives him a new loyalty and respect to Rhaenyra's crown.
